[0053] Preferably, the guide switch 35 and the exit switch 36 are located on the handpiece 2. When the handpiece 2 is held, the guide switch 35 and the exit switch 36 are close to the thumb position for easy operation.

[0054] Preferably, during the operation, the patient lies on his back or sits slightly with his back tilted back, and the operator inserts the laryngoscope blade 1 at the patient's head or on the side of the patient's head. The laryngoscope blade 1 is aligned with the axis of the patient's throat, and the handpiece 2 is not on the same axis as the patient's throat. The operating space is large, the operating range is selectable, the operation is flexible, and the adaptability is good.

[0055] In a preferred embodiment, the guide piece 34 is an elastic piece that is horizontal when unconstrained and curved when constrained. The structure is simple and made of stainless steel. When constrained by an external force, the guide piece 34 is horizontal and curved when constrained. This facilitates cooperation with the curved guide groove 12, preventing it from getting stuck while sliding along the curved guide groove 12.

[0056] In a preferred embodiment, the tube clamping mechanism 4 comprises a clamping piece 41, a grommet 42, a fixing ring 43, a release cable 44, and a trigger 45. The release cable 44 passes through multiple grommet 42 on the clamping piece 41, and its ends are connected to the fixing ring 43 and the trigger 45, respectively.

At this time, the position of the trachea deep into the patient's throat can be observed on the display screen 52. When the front end of the trachea reaches the appropriate position in the patient's throat, the guide switch 35 is released.

[0070] S5, remove the laryngoscope, pull the trigger 45 to tighten the release rope 44, pull the clamping piece 41 to open and approach the tracheal groove 11, and the trachea is released from the clamping piece 41, and the trigger 45 is released; press the exit switch 36, the micromotor 31 drives the gear 32 to rotate and drive the rack 33 to retract the guide piece 34 toward the insertion end 13 of the laryngoscope blade 1, and the grommet 42 slides along the release rope 44; at this time, the retracted position of the guide piece 34 can be observed from the display screen of the display 52. When the front end of the guide piece 34 retracts to the guide groove 12, release the exit switch 36, and pull out the laryngoscope blade 1. At this time, the front end of the trachea is located at the patient's throat. This method is simple and convenient to operate and can quickly intubate and remove the laryngoscope in a very short time.

[0071] The quick-guide intubation laryngoscope as described above is installed and used by connecting the handpiece 2 to one side of the push-in end 13 of the laryngoscope blade 1 on two different intersecting axes, the guide piece 34 of the guide mechanism 3 slides in cooperation with the guide groove 12 of the laryngoscope blade 1, the clamping piece 41 of the tube clamping mechanism 4 is connected to the guide piece 34 and is located in the tracheal groove 11 of the laryngoscope blade 1, the camera of the visual system 5 is located at the insertion end 14 of the laryngoscope blade 1, the display 52 is connected to the handpiece 2, the tube clamping mechanism 4 clamps the trachea or releases the trachea, the guide mechanism 3 drives the guide piece 34 to drive the trachea deep into the patient's throat, and the visual system 5 observes the scene during tracheal intubation in real time, with a large operating space, flexible operation, stable intubation direction, short intubation time, and good comfort.

[0072] During production, the laryngoscope blade 1 has an arc-shaped structure, the tracheal groove 11 is located on the outer arc surface, the tracheal groove 11 and the guide groove 12 are connected to each other, extending from the pushing end 13 of the laryngoscope blade 1 to the insertion end 14. Before intubation, the trachea is located in the tracheal groove 11.

[0073] During use, the micromotor 31 drives the gear 32 to rotate and push the rack 33 to drive the guide piece 34 to extend and retract along the guide groove 12, and the clamping piece 41 fixed on the guide piece 34 clamps the trachea, making the direction of tracheal intubation stable and reliable, shortening the intubation time, and improving the patient's comfort.

[0074] When in use, the micromotor 31 is located in the motor cavity 21 of the handpiece 2, and the gear 32 connected to its output end penetrates into the laryngoscope blade 1 and engages with the rack 33 connected to the guide piece 34. The guide switch 35 and the exit switch 36 of the micromotor 31 are located on the handpiece 2. When the guide switch 35 is closed, the micromotor 31 drives the guide piece 34 to extend, and stops when released. When the exit switch 36 is closed, the micromotor 31 drives the guide piece 34 to retract.

[0075] During production, the guide piece 34 is made of stainless steel and is in a horizontal state under external force constraints. After being constrained by external force, it is in an arc shape, which is conducive to cooperating with the arc-shaped guide groove 12 so that it will not get stuck during the sliding process along the arc-shaped guide groove 12.

[0076] During use, the trigger 45 is pulled to tighten the release rope 44 and pull the clamping piece 41, so that the opening of the clamping piece 41 expands to release the trachea.

[0077] Before the laryngoscope is inserted into the patient, the trachea is placed in the clamping piece 41 from the side of the opening of the clamping piece 41 and is clamped. The trachea is bent and pressed against the guide piece 34. After the trachea penetrates into the patient's throat, one end of the release rope 44 passes through the rope ring 42 on the clamping piece 41 and is fixed to the fixing ring 43, and the other end passes through the rope hole near the pushing end 13 of the laryngoscope blade 1 and is fixed to the trigger 45. When the trigger 45 is pulled, the release rope 44 is tightened, pulling the open end of the clamping piece 41 to open and release the trachea.

[0078] When in use, the fixing ring 43 is close to the insertion end 14 of the laryngoscope blade 1, and the release rope 44 passes through multiple grommets 42 connected to the clamping piece 41. When the release rope 44 is tightened, the grommets 42 are pulled synchronously, so that multiple clamping pieces 41 are opened at the same time, which is conducive to releasing the trachea in a very short time.

[0079] When in use, the control switch 53 controls the opening and closing of the display 52. After the display 52 is opened and closed, the camera 51 is in working state, timely obtains the captured scene, and transmits the scene to the display screen of the display 52, so that the operator can observe the intubation conveniently.
